Abstract To improve the detection speed of cow mounting behavior and the lightness of the model in dense scenes. this study proposes a lightweight rapid detection system for cow mounting behavior. Using the concept of EfficientNetV2. a lightweight backbone network is designed using an attention mechanism. https://www.ngetikin.com/super-value-1-2-in-Tobacco-Road-Acacia-Distressed-Engineered-Hardwood-Flooring-4-8-in-Wide-Sample-quick-super/
